We divide 453871 by 15
Our goal is to divide 453871 by 15.

Let's proceed to step 1:
15 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 15

On to step 2:
15 can be fit into 45 3 times, resulting in a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 45 from 45 leaves us with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 15

Advancing to step 3:
If we divide 3 by 15, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 30.0
If we subtract 0 from 3, we get 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 15

Advancing to step 4:
15 goes into 38 2 times with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 302.0
Subtract 30 from 38 to get 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 15

Step 5:
When dividing 87 by 15, we get 5 with a remainder of 12.
Record the quotient 5 as the next digit in the result. 
Result so far: 3025.0
The remainder is 12 after subtracting 75 from 87.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 15

On to step 6:
If we divide 121 by 15, we get 8 and a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 30258.0
If we take 120 away from 121, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
15 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 30258.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
If we divide 100 by 15, we get 6 and a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 30258.06
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
If we divide 100 by 15, we get 6 and a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 30258.066
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 30258.066 and a remainder of 0.001.
